Wow! That is amazing feedback from the Endocrinology conference. Also good to hear that your doctor is willing to increase your med to relieve symptoms. Please keep us up to date on your further progress.
****UPDATE*****
I like to share updates on the results of my posts in case others stumble upon them looking for answers.
Saw Endo today and she DID agree to increase my dose and stated she would continue to do so until I felt better and was higher in the FT4 and FT3 ranges. I was totally shocked, as I was prepared for an epic battle to ensue since my TSH below lab range.
Interestingly enough, she said that she just returned from an Endocrinology conference and was discussing how there is more talk about managing symptoms and FT3 and FT4 levels versus the TSH. So....there is hope that maybe SOME endocrinologists are starting to see the light. Its early, but maybe some are finally starting to look at symptoms and not just labs and adjust meds accordingly. At least mine is.......
Your levels are not high enough to worry about RT3 when increasing your T4 dosage. There are other factors affecting conversion to RT3, but increased conversion to RT3 is also a common defense mechanism of the body to prevent excess FT3, which you don't have. Ferritin is a variable that can affect conversion of T4, so you need to increase supplementation with iron to get your ferritin optimal, which for women is about 90 minimum.
Yes, to that. As stated above, "serum thyroid hormone levels are the sum of both natural thyroid hormone and thyroid med. As thyroid med is increased, TSH goes down, and the output of natural thyroid hormone also goes down. Only when TSH is suppressed enough to no longer stimulate natural thyroid hormone production will serum thyroid levels reflect further increases in thyroid med."
Also there is scientific evidence that the majority of hypo patients will have suppressed TSH levels when taking adequate thyroid med. And in the words of an excellent thyroid doctor, "In the best tradition of clinical medicine, a physician should prescribe thyroid hormones as needed to eliminate the symptoms and signs of hypothyroidism without producing any symptoms or signs of thyroid hormone excess."
If that Endo is your only option for a thyroid doctor then you are going to have to provide enough contrary information to persuade him that concerns about suppressed TSH are unfounded, and that you need your med increased as needed to relieve hypo symptoms.
A suppressed TSH is an indicator of possible hyperthyroidism only during initial diagnosis. After therapy with thyroid med is started, TSH becomes basically irrelevant. Our bodies evolved with the expectation of a continuous low flow of thyroid hormone from the gland. When a hypo patient takes their total daily input of thyroid med all at once, it has a suppressive effect on TSH. In addition, serum thyroid hormone levels are the sum of both natural thyroid hormone and thyroid med. As thyroid med is increased, TSH goes down, and the output of natural thyroid hormone also goes down. Only when TSH is suppressed enough to no longer stimulate natural thyroid hormone production will serum thyroid levels reflect further increases in thyroid med. You can read about this starting with Rec. 10 and 11 starting on page 13 of the following link.

In the paper you can also read in Rec. 13 that there are scientific studies showing that TSH is frequently suppressed below range when a treated patient is taking adequate thyroid med. That does not mean hyperthyroidism, unless there are hyper symptoms due to excessive levels of FT4 and FT3.
You can also find in Reference 36, page 24 the following scientific evidence that totally refutes the use of TSH to try and assess the clinical status of a hypothyroid patient.

Are Biochemical Tests of Thyroid Function of any Value in Monitoring Patient Receiving Thyroxine Replacement? BMJ 1986;293(6550):808-10
“Measurements of serum concentrations of total thyroxine, analogue free thyroxine, total triiodothyronine, analogue free triiodothyronine, and thyroid stimulating hormone, made with a sensitive immunoradiometric assay, did not, except in patients with gross abnormalities, distinguish euthyroid patients from those who were receiving inadequate or excessive replacement. These measurements are therefore of little, if any, value in monitoring patients receiving thyroxine replacement." Of 148 patients attending an outpatient clinic, 148 were classified by their clinical status by 4 qualified consultants with experience in thyroid disease. Of those 108 were classified as hypothyroid and from biochemical testing, their TSH ranged from 0.1 to 19.7. The TSH for 22 patients classified as hyperthyroid ranged from 0.1 to 14.4. The TSH for the 18 patients classified as hypothyroid
ranged from 0.1 to 123.5.
Clearly TSH has no value in determining thyroid med dosage.
I know gimel is going to give you great advice, so I'm not going to get involved in that... I just couldn't help noticing how similar your labs are to my own and the fact that my own endo is only concerned with TSH and took away my T3 med, as well.
It makes me wonder if we could have the same endo, or at the very least, if they went to med school in the same class... :-)
Vitamin D 60 ( optimal )
B12 800 (over range, but accepted)
Ferritin low at 20 , but improve since January where it was a 6.
Ferritin has been low for many years something I'm working on . In a nutshell I'm 20 months postpartum and prior to my pregnancy had my free T3 and free T4 levels in the 50 to 70% range and felt great . Postpartum I can't seem to get up to those levels and endocrinologist is too worried about the TSH .
Before discussing further, I have a couple of questions for you. Do you take your thyroid med in the morning before blood draw? Have you been tested for Vitamin D, B12 and ferritin? If so, please post those results.
